Musar for Lamentations 3:38

And from this, we will understand very well what has disappeared from the eyes of researchers in what they have examined regarding, heaven forbid, a change in God's will. The Almighty decrees a decree and then repentance, prayer and charity can change that to the better; and sometimes it changes from good to bad. But they walk in darkness because there can be no change, heaven forbid. Rather all is one and is only a matter of one desire. That is to say this inquiry is a matter of faith. I will also copy what I wrote as a child in my pamphlet, even though it is a little different. In any event, it all goes together in one place. These are my words. Written in section of Godliness in the gate of unity. And the whole faith of unity is complete; as there is no body nor strength of the body, nor a separate mind, and will not change from thought to thought or from action to action or from one leader to another. It is a complete intellect and simple and unique in all parts of His names and in all attributes. And a change in actions on the part of the leadership only exists from the side of the recipients. Because the one who walks in innocence and straightness, and keeps a good home, receives goodness derived from God Almighty. And he who perverts his path and distances himself, is distanced from the good derived from God and the opposite is derived from Him.

Basically, the Torah speaks about blessings and curses. In the Celestial Regions both blessings and curses originate in the same domain. There is total unity, i.e. there really is no curse. Whatever originates in the most remote recesses of the Celestial Regions is only blessing. Curses occur only when the recipient or intended recipient of the blessings has forfeited them through his behavior. A blessing is a sign of a normal development, i.e. blessing is channeled from Heaven earthwards. The evil some people experience, and which they ascribe to an outpouring of curses from Heaven, is merely a blessing which these people are not able to cope with due to their faulty disposition. This approach helps us to understand Lamentations 3,38: מפי עליון לא תצא הרעות והטוב, that this is not the order in which blessings and curse emanate from above. On the contrary, the order is הטובות והרע, first the good and then the evil. Everything emanating from G–d is originally good. Not everything which is evil originates from G–d. עוז וחדוה במקומו, (Chronicles I 16,27) "Strength and joy are in His place." This tells us that what is good remains inviolate. Only evil is subject to evolution. One of the reasons that we the Jewish people are called ישראל, is because due to our origin in Heaven we are part of the Divine, though on earth we have become separated from the Divine because of the fact that we now possess bodies. The opening words of the פרשה, i.e. ראה אנכי, are in the singular because they point to our Divine origin. When the Torah switches to the use of the plural, i.e. לפניכם, this is in recognition of the fact that we have become composed of a great variety of differently oriented beings. The same applies to the way the Torah prefaces the blessings in the singular before switching to the plural. The curse will happen only אם לא תשמעו, "If you (pl) will not listen," an allusion to the lack of unity.
